Accessibility checking

Rocket Validator looks for accesibility violations on your pages using the axe-core accessibility engine, hosted on our own servers and integrated into our web crawler. You don't need to buy an additional license, everything's already included in your Pro account at Rocket Validator.

WCAG: 1.3.1: <li> elements must be contained in a <ul> or <ol>

All list items (li) must be contained within ul or ol parent elements.

For a list to be valid, it must have both parent and child elements. Parent elements can either be a set of ul tags or a set of ol tags. Child elements must be declared inside of these tags using the li tag.

Screen readers notify users when they come to a list, and tell them how many items are in a list. Announcing the number of items in a list and the current list item helps listeners know what they are listening to, and what to expect as they listen to it.

If you don't mark up a list using proper semantic markup in a hierarchy, list items cannot inform the listener that they are listening to a list when no parent is indicating the presence of a list and the type of list.
